Abstract (en)

[origin: WO2022051882A1] This document generally relates to use of intelligent reflecting devices for positioning in wireless communication systems, which may increase the coverage for a wireless access node or base station. During a positioning session, an intelligent reflecting device may reflect a signal to a receiving node. An identity of the intelligent reflecting device may be determined, and a position of the receiving node may be determined based on the identity of the intelligent reflecting device.
